Ticket-based Gantt chart and calendar

Description

Compared to TracJsGanttPlugin, this plugin does not compute the completed percents from custom ticket fields like 'remaininghours' or 'estimatedhours' but you set the completion value in the range of 0 to 100% in the ticket form, manually.

The meaning of start and end date of a ticket displayed in the chart is at the discretion of you. Usually, you set the planned time period, though you cannot see in the gantt chart if completion had started earlier than planned, was interrupted or has finished later. For a review of the work history, you may interpret start and end date to indicate the worked time period. This is up to you.

Query about parents, blockers, milestones. These features do not seem obvious. Blockers has a name sufficient to suggest task dependencies/prerequisites: how are they modeled & what consequences ensue? (A pet peeve is that IMO "blocking" should preclude work on the downstream task, else what's the POINT of the relationship? Parent meanwhile suggests heirarchy or abstraction, but again I don't see the connection to any consequences in operation or display. I guess this is a documentation request.
